Final answer:
Regular altimeters lack a barometric setting to compensate for weather-induced pressure variations, which sensitive altimeters used in aviation have.
Step-by-step explanation:
Regular (nonsensitive) altimeters have no capability to compensate for changes in barometric pressure due to weather changes. An altimeter is an instrument used to measure the altitude of an object above a fixed level. The standard altimeter in aviation is a sensitive altimeter, which has a barometric setting that allows the pilot to adjust for pressure variations and is calibrated to assume a standard atmospheric pressure at sea level. However, a nonsensitive altimeter lacks this feature and is typically used in less dynamic environments, such as modeling or hobbyist activities, where precision is not as critical.
